The B39741B7924P810 is a SAW (Surface Acoustic Wave) filter manufactured by EPCOS (TDK). SAW filters are critical components in radio frequency (RF) systems, responsible for selectively passing desired signals while rejecting unwanted signals and noise. They are commonly chosen for their compact size, low insertion loss, and sharp frequency selectivity.

Applications:

• Wireless communication systems (e.g., Bluetooth, WLAN)
• Mobile phones
• Remote control systems
• Satellite communication systems
• ISM band applications

Features:

• High selectivity: Provides excellent rejection of out-of-band signals.
• Low insertion loss: Minimizes signal attenuation within the passband, preserving signal strength.
• Compact size: Enables integration into small electronic devices.
• Surface mount technology (SMT): Facilitates automated assembly.
• Stable performance: Maintains consistent characteristics over a wide range of operating conditions.

Benefits:

• Improved signal quality: Enhances the performance of wireless communication by reducing noise and interference.
• Extended communication range: Minimizes signal loss, allowing for greater distances.
• Reduced power consumption: Improves energy efficiency by selectively filtering desired signals.
• Simplified circuit design: Integrates filtering functionality, reducing the need for discrete components.
• Enhanced reliability: Ensures consistent performance in diverse operating conditions.

Additional Details:

SAW filters, such as the B39741B7924P810, rely on the piezoelectric effect, converting electrical signals into mechanical waves (surface acoustic waves) on a piezoelectric substrate. The specific frequency response is determined by the design of the interdigital transducers (IDTs) on the substrate. The SMT package is designed for automated assembly. EPCOS (TDK) is a well-regarded manufacturer of high-quality electronic components. Detailed information about the center frequency, bandwidth, insertion loss, and impedance characteristics is generally available in the product datasheet. This particular component is listed as END-OF-LIFE, implying it is no longer actively in production but could be available from distributors or within existing devices. Similar devices function in the MHz to GHz frequency range. Compliant with RoHS standards.
